Ask HN: How to do simple heartbeat monitoring?
Hey there!

My team is hosting an API that sends open telemetry data to Signoz & manages on-call via PagerDuty. We've configured Signoz to hit Pagerduty when there's a series of 500 errors.

However, our server went down last night and NO opentel data was sent to Signoz. We weren't notified that the server went down as there weren't 500 responses to report. What's the easiest way to have a cron-like query hit our API and integrate with our existing stack? Is this feasible with our existing vendors? Should I have a serverless function running on a timer that uses Pagerduty's API? Should I be migrating to another monitoring service?

Any advice would be appreciated!
but date and clock_gettime are still accessible and not much more overhead than the Mach API call. Additionally as I mention in another comment, this would have to be about Meltdown, not Spectre, and Meltdown is mitigated in the kernel through other techniques without sacrificing timers.

In addition, if you get caught lying about this, your app may be nuked and your developer account terminated. May not be a big hurdle, but definitely can hurt if you have many users.
You've made it so deep into this discussion and now is when you pull out the "paid troll" comment? Speak directly and don't imply things you're not confident enough to say outright. And frankly, 99% of claims of paid trolls sound like conspiracy theories to my ears.
I think it matters a lot more for commercial mortgages. In any event, it's like 20-30bps or less according to the Fed. So higher, but not that much higher even for commercial mortgages, and even less for residential where there's a lot more federal protection going on.

The bigger impact, I believe, is that housing prices can go more crazy. People will take more risk if they know they can walk and leave the bank holding the bag, so there isn't that limiting factor on prices.

(Though I suspect, but obviously can't confirm, that the effect from non-recourse mortgage is absolutely dwarfed by other factors, especially out here on the west coast where we have very restrictive zoning policies, weaponized environmental policies inside urban areas, etc)

The actual claim was "UI colors can have different meanings in different cultures."

I don't know about that prosperity thing, but I can give you an example that happens a lot. Some groups use red to mean stopped and green to mean moving, while others use red to mean danger and moving, and green to mean safe and stopped. This isn't directly country-related but I believe there's significant variation based on location.

Oh, wait, while searching to double check that I found an example of exactly what you asked for. CJK stock market displays tend to use red for increases, while the West uses red for decreases.

The very sight of the word "trial" makes a bad impression on me. It puts me on the defensive. I'm immediately reminded that I'm being sold a product, rather than offered a solution.

I stop thinking about the task I was working on, or what lead me to the product in the first place, and start worrying about the details of the trial.

"Am I going to need to enter credit card information to start the trial?"

"Will any images I create be watermarked unless I pay a premium?"

"Are the features I actually need even available within the trial, and are they actually useful during that time?"

I don't want a free trial of anything, ever. I'd rather have a free, community-supported version and a premium version with official support. Or a basic version with free, unlimited access to only the most basic features, and a pro version with more advanced features at a cost.

I just need something I can actually use without worry, and when my use case extends beyond the most basic of features, or the software becomes an important part of my daily workflow, I'll happily pay (and I have) for a more powerful version.
> Article does not say that. After several paragraphs it could be implied with mention of LLC ? There is also examples given of Venia . So I would not say exclusively about US at all.

Don't be obtuse. They're obviously speaking about the US legal system, some of the comments listed signed with US locations, and if you look at the article two entries down in their blog that refers to "the housing market," they only cite US statistics.

> And I just say , lots people claiming its good money , quite profitable, so we can look forward to lots new investors that are attracted to this profitability.... but it does not seem to happen. Why?

What in the world are you talking about? Real estate is one of the most, if not the most popular long-term investments in the United States? If nobody invested in real estate when why is the market so tight? Do you even think about this critically for a moment before you type it out?

And once again, ZERO evidence of these so-called expenses. I'm not even talking about receipts, I'm just asking for examples for regular expenses large enough to change the nature of this debate. Of course, they don't exist. You are either willfully ignorant, genuinely ignorant, or lying.
I think you're drastically underappreciating the impact of promotion and discoverability on public discourse.

The internet / web has never been a platform where all had equal access to share their views. The ability to speak doesn't matter if few can hear you.

When it was more democratic in the early days, the masses weren't part of it.

When the masses came online, promotion and discoverability had already been centralized by large platforms.
To be clear, I think they should have updated their liveblog to add a link to the subsequent Hamas statement calling its accuracy into question. That said, I think some of this comes into questions about the format - this wasn’t a specific story but one of many breaking news details in a tumultuous event, and it’s far from unprecedented within the industry.

As a good example of how messy this can be, consider this story:

https://www.nytimes.com/2023/12/28/world/middleeast/oct-7-at...

They fairly quickly ran into some problems with reliability of one of the key witnesses which reached the point where a number of journalism professors wrote an open letter: https://www.thenationalnews.com/news/us/2024/04/29/journalis...

There’s a rundown with many links here: https://mondoweiss.net/2024/01/family-of-key-case-in-new-yor...

None of that is mentioned on that story and the only correction is a minor detail.

Now, to be clear, I am not saying that it’s okay for Al Jazeera to be sloppy if the NYT is sloppy but rather that we should be consistent in our standards and they should probably be higher for everyone. The public and especially people covered in these stories deserve better.
Interesting! Not compelling because you already have your own answers to the questioned posed? Or perhaps not compelling because you don't find the questions to be interesting/relevant?

The value of this story, in my opinion, isn't just that these are neat things to think about. There are deep unanswered questions here that challenge how we understand the connection between materialistic science and a non-materialistic belief in "self", and push the limits of theories of ethics. For example, right up to the very end it keeps throwing new questions at you, such as "What is justice when 'two' people have identical claims on a fundamental right? Namely, which of them gets to keep the body? Which of them gets the estate? Which of them is married?"

Dennett's story is a powerful instigator of thought on these topics.

There is no accusation of fraud here. What seems to be happening is, as with similar enforcement actions, Robinhood is being dinged for trading securities improperly, without ticking off the legal requirements for notification, tracking, authentication, etc...

The idea that crypto assets aren't "securities" and thus not subject to SEC regulation is, and always has been, laughable. Virtually everyone trading these things is doing so to engage in arbitrage of fungible assets to make money. I mean, come on.
Do you believe it's possible to support Ukraine, criticize and blame Russia for the conflict, and still think there's much to criticize about the Ukrainian response? It seems like you're not comfortable with that level of nuance, and you're being very disrespectful as a result.

No less a scientist than Roger Penrose is (arguably) in that camp: his excellent “The Emperor’s New Mind” is about the paradox of free will in a mechanistic universe, and the question of where among the laws of physics might consciousness fit. (Spoiler alert: the collapse of the quantum wave function has a different character from all the other laws.)
I would really welcome more experimentation in the cluster process management space. Right now it's Kubernetes, Nomad, or solutions embedded into applications (e.g. cephadm).

It's a shame that this is an exact copy in a different language.

Kubernetes is nice but I can't wait to see what the next generation of tools will look like.
It's because the scientific community has much more influence over the society than the so called influencers. Scientific community's pride is the peer review system, thus if anyone is found to be corrupt they need to be quicking on calling them out. People in general know that influencers can be selling bullshit, but do not expect licensed doctors or scientists to be selling them too.

Apple is partly to blame here. One big problem is that there are so many false positives for the "A new iPhone/iPad has access to Facetime/iMessage on your account" warning -- a message that can easily be triggered on all your devices by an automatic upgrade on one of them. If you have an iDevice that is online but not used often, you'll be surprised by this message every few months.

This problem either causes undue concern on behalf of the account holder, or trains them to dismiss these messages without verifying the potential intrusion. Neither are good outcomes for security of the Apple account.

The latter isn't much like OG mango, fair warning, but you'll probably like it if you were a fan of the old school.

The trick with refilling is to press the sides in when replacing the rubber stopper. If you do it right, you'll see a bubble or two rise up from the bottom. If you skip this part it will leak everywhere. Also, blow through the cart several times to clear the tube. It's a bit fiddly at first, but you'll get the hang of it.
adding just to counteract some very odd takes in here from I presume currently vapors or wildly uneducated non-nicotine addicts.

Nicotine addiction owned my life for years. Nothing like it. I still have dreams about relapsing dip and then saying “f-it” and spending a day in my dreams going wild with Cope.

Quitting meant trying to taper, trying the gum, trying pouches vs loose dip, and if vapes were around I’d prob have tried those too.

All that adds up to is you’re still addicted, just to a different form, and your day shifts when leaving the house from “keys, wallet, tin of dip, spitter bottle” to “keys, wallet, nicotine gum/vape/we.” You’re still owned by the chemical haha.

Only thing that worked for me and others I knew who quit for good was cold turkey and an awful 90 days, at which point the habit and the chemicals are basically broken.

Which brings me to my point:

The amount of free marketing Juul and co is getting in this thread from nicotine addicts and their supporters over how Juul is fine and much much different from the good ol’ American diet cigs and dip is disappointing and not surprising.

The 10-20 y/o brand new chemical that is extremely addictive and associated with centuries of health problems is now totally fine? Where have I heard that one before……? At least make Philip Morris’s job hard, please.
When that one customer is "your family", it's a little bit different, though.

> Why is economics stuff so hard?

The basics aren't hard. But also not particularly useful outside of the work of economists. That is no doubt the problem you keep seeing: 'i think that this economic thing is broken [because I cannot find any applicability in my daily life]'.

Economics can become hard as it is ultimately a study of human (possibly animal) behaviour, and these creatures seem erratic to our limited understanding.
Yeah, this feels more to me like Whiskey vs Bourbon where it's just standards and locations differing much of the two.

I thought it was going to be more like wasabi, where most places just serve green horseradish.
I can highly recommend Better Stack. We have never been let down by their service.
Not mutually exclusive just one situation the barrier is not having the money in the first place and the other the barrier is exercising the self control over the thought "I have the money, I can get this now". It's a common hurdle for those who've grown their income and a pretty decent problem to have (as far as problems go).

Cost of Constructing a Home- 2022 (NAHB)
Provided as an article submission because:

1) Global housing shortage (apparently now hinders world immigration according to Bloomberg)

2) Official study that provides reference numbers on actual costs (at least for America).

3) It's a VC website, there's probably a bunch of optimizations and business possibilities. Probably even some "tech" VC. Housing costs also jumped $100,000 in the last 3 years of the study apparently (the framing by itself is more than most other categories).

4) It might provide interesting discussion on house building, house costs, or realty / construction utilities in America

> Why not just disenfranchise and/or murder any non-French person within the borders of the French people's native land?

Historically?

Because post-revolutionary France has been a militantly-secular state.

And a decent counter-example on why conflating a state with a specific ethno-religious identity is a terrible idea.
There's collision avoidance systems, but those are really for "not flying into another plane". You're going so fast that by the time you can pick up that you're about to hit a drone or bird, you've destroyed it -and possibly yourself- already.

Military drones are a different matter: you will never find yourself in the same air space, because you will never be told they're there. They are ghosts, much like airplanes that run without a transponder "because it's legal". You don't see another aircraft unless you know exactly where to look, or you're right on top of them.
As an Indian-American, "South Asian" is a perfectly reasonable ethnic grouping in the United States. Collectively, that represents ~1% of the US population, too small a grouping to reasonably split out when talking about ethnicity in general terms.

All cultures are fractal. For my own ethnic heritage, for example, I could insist on splitting out:

* South Indian Dravidians from North Indian Arynans

* Kannadigas from other South Indians

* Lingayats from Vaishnavites

But that level of detail (absent special contexts where its relevant) would almost always confuse rather than clarify.
> Did Al Jazeera report on it?

Yes, yes they did:

For my applications, monitored by prometheus + grafana, we have alerts when no data is reported for certain metrics in the past 5 minutes, indicating a malfunction in the subsystem.

With a metric, you can use a monotonic counter to serve as a heartbeat. A timestamp would work. In your monitoring system, when the heartbeat value has not increased in X minutes, you alert.
Lockdown mode? I might as well surf the web in a Linux terminal and use a flip phone.
That is exactly the point. As a producer of the said software, if that is the user's usage pattern, and there are enough regular users to sustain/pay for these users, then I won't want to charge them. Doing so means I either lose out on potential customers or they aren't going to be a true customer anyways.

> But that's exactly what you described yourself as doing. You downloaded the software, used it, found that it satisfied your needs, and were familiar enough with the software to recognize that you needed it again three months later.

That's not what happens. I download it, use some tiny part of it once (like the noise reduction filter of a full audio editing suite), forgot about it, googled noise reduction 3 months later, discovered I'd already installed it 3 months ago, and now can't try it with a different file because the trial expired.

> The real bizarre thing is that someone can blame the software provider for giving away free use of their software, or for "only" allowing them to use it for 30 days for free.

But they deserve the blame, because now I'm going to go download a different audio editing suite to try their noise reduction instead. And if now I keep having to do noise reduction because it's no longer a one-off thing, I'll purchase that competitor. Because the first piece of software stopped letting me try it out so I can't even compare anymore. Even though I'd only used it for 5 minutes.

My whole point is that "30 days for free" is meaningless if I only use it for 5 minutes. It makes much more sense for trials to be usage-metered rather than contiguous calendar days.
No it doesn’t. Higher performance APIs like Date and clock_gettime are still available and not specially privileged and 40x faster. This looks pretty clearly like a bug.

Spectre mitigations also are really silly here because as a swift app you already have full access to all in-process memory. It would have to be about meltdown but meltdown is prevented through other techniques.
Certainly -- I'm just not sure who would "authorize" it in the first place.
> The most comparable recent US engagement was destroying ISIS in Mosul.

My point wasn't that the US is better. My point was that there were widespread protests opposing the US's "collateral damage" in their wars after 9/11 and Israel is doing worse.

The number you're citing is also the effective ratio based on the reported deaths, not an official or leaked guideline and this wasn't "the US" but "the US-led Iraqi Security Forces" (not a Western military, even if it is in practice US-led). The tweet you cite also references a Pacific battle between the US and Japan in WW2 (when the US infamously dehumanized the Japanese to an uncomfortable degree - surely the nuclear bombs trump that battle in terms of civilian casualties) and a battle that was part of the "Korean War" which in retrospect has become infamous for its war crimes, mostly committed by the US.

These are battles of infamy. You don't get a medal for being better than that, those are the table stakes if you want to shout about being the "most humane military".

Also, the reason I called 30,000+ the "lower bound" is because the process used by the "Hamas-run health ministry" is extremely conservative (it's not just a tally - the "fake deaths at hospital parking lot" story everyone ran with was a translation error into English that conflated "injured" and "deceased") and seems to have broken down earlier this year along with the remaining infrastructure in Gaza.

> The IDF has a robust decision making process, in excess of a single “ratio” approach.

That's a no then unless you think other militaries don't have decision making processes.

I'm not going to engage with you further as we seem to have either fundamentally opposed value systems or fundamentally opposed perceptions of reality.
This basic monitoring primitive is the first thing we started with at Cronitor[1]. I was a software engineer at my day job and needed a way to be alerted when something doesn't happen.

We have a decent free plan that would probably work for you.

Defining a Single Enumerant
I recently moved to complete Linux, no dual boot. I was planning to set up League of Legends on Linux, so I could continue to play, but since Vanguard (the anti-cheat software) got released, that is no longer possible. I was a League player for 10 years. I really enjoyed playing the game.

Riot is not implementing the same kernel anti-cheat for Mac. In their blog post, the noted that there are about 800 users playing League through Lutris. If they can detect this, why can't they just allow Linux users to play without the kernel anti-cheat.

I don't think there is a single League of Legends player in the world that wants a kernel anti-cheat. Riot did it anyway. They are completely out of touch with their user base. How are people supposed to trust a kernel anti-cheat from company that is owned by a Chinese company, Tencent.
